Explanation:

Step1: Multiply the coefficients

Multiply \(1.4\) and \(2.7\).
\(1.4\times2.7 = 3.78\)

Step2: Add the exponents of 10

For \(10^{5}\) and \(10^{4}\), use the rule \(a^{m}\times a^{n}=a^{m + n}\).
\(10^{5}\times10^{4}=10^{5 + 4}=10^{9}\)

Step3: Combine the results

Multiply the result from Step1 and Step2.
\(3.78\times10^{9}\)

Answer:

\(3.78\times 10^{9}\) (So the first box is \(3.78\) and the second box is \(9\))
